Like his promise that everyone would have great health coverage with Trumpcare? His latest proposal would lose 30+million coverage...
Trump only cares about what the space program can do for him, and him alone... and he is willing to risk lives to do it... like putting astronauts on the Orion Test flight.

In February, at the request of the Trump administration, NASA began studying whether it was possible to add crew for the first flight of its Space Launch System, a heavy-lift rocket under development for deep space missions.

On Friday, the space agency announced it would not. During a conference call with reporters, Robert M. Lightfoot Jr., the acting NASA administrator, said the change was technically feasible, but that the additional cost, time and risks outweighed the benefits. “It really reaffirmed the baseline plan we have in place is the best way to go,” he said.

Putting astronauts on the first flight would have added $600 million to $900 million to the $24 billion price tag, Mr. Lightfoot said, and delayed the launch until probably the first half of 2020.

Including astronauts would have also required significant work, like adding a fully operational life-support system to the Orion crew capsule, where the astronauts would have been seated.

And he has no comprehension of the realities involved...

TRUMP: “Tell me: Mars, what do you see a timing for actually sending humans to Mars? Is there a schedule and when would you see that happening?”

WHITSON: “Well, I think as your bill directed, it'll be approximately in the 2030s. As I mentioned, we actually are building hardware to test the new heavy launch vehicle, and this vehicle will take us further than we've ever been away from this planet.

“So, unfortunately space flight takes a lot of time and money so getting there will require some international cooperation to get the — it to be a planet-wide approach in order to make it successful just because it is a very expensive endeavor. But it is so worthwhile doing.”

TRUMP: “Well, we want to try and do it during my first term or, at worst, during my second term, so we'll have to speed that up a little bit, okay?”

Besides, He really doesn't have the stamina required when he tires himself out on twitter feuding with morning show hosts...
